Nice trick if you can do it

Pulled the axles on the truck and found one of the studs on the spider twisted off about 1/2 " deep in the hole. I think the only thing holding it and the nut was the gasket maker used on the flange. Went to the NAPA dealer seems they do not do any stud removal or much machine work anymore. They referred me to a young man that has a weld shop on his dad's farm. He drilled a 3/8" hole thru the stud started welding inside the hole in the stud continued up inside the hole without touching the sides or the threads then welding a nut on top. After cooling it came right out.

what a great idea I wish I could say I could do that but my hand would be all over the place

The matter of the trick is weld pulls the stud walls to its center when getting colder and makes a stud thinner that way.

So after welding a nut a stud comes relatively free.

It's too difficult to weld inside a deep hole starting from its bottom though.

Thats the same process that Mack recommends to remove broken stainless exhaust manifold studs in ASET AC engines. The welding rod that is used is not standard rod like 7018.

That's how I pull bushings from a lot of equipment, get the pin out then start Welding inside the bushing all the way around. Most of the time after the second or third pass it will make a pop and you can pull it right out.
